ThisWork-rest has a stem 4:1 adjustably held by a set-screw 43 in a socketin a member 45, the stem; 47 of which is held bya set-screw 49 in asocket in the head 29 which is at right angles to the ock t-" he m mberW th s. c struction the work;res t may be adjusted in directionsparallel to the stems 41, 47 and ngularly bo h x s of t st Located abovethe cutter is. a trough '51 having leading from its lower end a pipe 53the outlet; of which is a pieceof felt 55 held in contact withthecutter. Above the trough is a reservoir 57 for oil having in itslower end an outlet cock 59. The purpose of the, construction justdescribed is to lubricate the cutter so as to improve its cutting actionon the rubber. Mounted in the rear of the cutter is a grinder 61 whichmay be moved into and out of contact with the t e by rn g a fing eho d'Although the machine is capable of op-' ating up di fe ent ype o o s, hr

has been shown a shoe comprising a welt 100 to which is stitched aslip-sole 200. After the slip-sole has been stitched in place, the

edges'of the welt and slip-sole are trimmed,

. in any suitable manner as for example by the use ofaa rough-roundingmachlne, to

the desired contour so that the edges of the welt and slip-sole registerwith each other of the welt and slip-sole. The shoe is preferablypresented to the machine bottom side up, as shown in Fig. 4, with thewelt resting upon the support 37. It will be noted that the edge gage 39does not appearin this figure. This is'because the gage, as shown in.Figs. 2,3 and 4, decreases ,in height at its forward end until, atorabout the cutting point, it does not project at all above the upperportion of the support 37. Referring to Figs. 3 and 5, the effectiveportion of the gage is approximatelythat portion which is forward of thepoint marked X. The common edge of the welt and slip-sole contacts withthe gage and thus determines the, course of the trimming cut inaccordance with the contour of that edge, the outsole projecting over the gageas the sole is advanced to the cutter. It will be noted that the edge ofthe support 37 is curved and that the gage 39 hasa similar curve. Thisis to facilitate the guiding ofthe work when curved edges are beingtrimmed and the shoe is consequently being swung more or less.

-:Although it has beens'tated above that the shoe is preferablypresented to the ma;

chine bottom side up, it is in some cases the practice to present theshoe right side up. For example, in the manufacture of womens shoes itiscustomary in some fac tones to incorporate in such shoes a crepe rubberoutsole which is sothin and consequently so flexible that it cannot betrimmed satisfactorily with the shoe presented to hema ine b tt s devup- In h case it has been found preferable to hold the shoe right sideup. The'fiexibility of the sole permits it, to bend upwardly and thus tobeheld against the edge gage 39; and, owing to the fact that the forwardend of the gage tapers downwardly at the locality in which the cuttingtakes place, this upturned edge will bend down somewhat at this localityand permit the cut to be made properly.

In'Figure 5 there is shown a member 71 made of resilient wire andfastened to the w rk support by having its inner end bent upwardly anddriven into a suitable socket injthe support. As the operator swings theshoe during the trimming operation, there is danger at times that he maymove one handinto a position where it would contact with the forwardportion of the cutter 9.

Before, however, this can take place, his" hand will contact with themember 71 which thus serves'asa sort of telltale to warnfthe operator ofdanger. V

Although the inventionhas been "set forth as embodied in a particularmachine, it should be understood that the invention is not limited inthe scope of its application to, the particular machine which has beenshown and described.
